"Strippers" they are often called, relate to the method of boat building is old and well perfected. It basically involves setting up a series of molds and then wrapping strips of wood around them. More specifically, I'm mostly using the method outlined in the book Kayakcraft which is a great set of instructions for anyone wanting to take on this type of project.

The wood for this boat is clear cedar that has been ripped into 3/4" x 1/4" strips. Each of those then get a concave and convex edge. This a great method because then each strip fits together perfectly at any angle seen on the plans.

The molds and raised construction surface are all made of particle board. It's cheap and easy to work with but you have to make sure it doesn't get wet. You can see in the photo how the strips fit over the molds.

Eventually, all the wood inside and out will be coated with a clear epoxy over fiberglass which ultimately will provide most of the strength and all of the water resistance.

The sail plan is going to be quite simple but could consist of either 1 or 2 sails. Each option has its benefits. Dividing the load of the wind between two sails would lower their center of effort and therefore lower their leverage on the boat. But, these are fairly small sails to begin with and, aerodynamically, larger sails are generally more efficient. So while having two sails would increase my stability, having one would likely increase the performance.
The option I will likely choose will be two large sails that can be easily reefed (or taken down). Then you could travel with one, or both if the wind was light.

This problem can be thought of as one of rotational motion due to force. As the wind pushes on the sail, the buoyant force and keel mass push in the opposite direction. So, if we can define all of the forces acting on the system, we should be able to say something about how the boat will react at certain wind speeds.
One problem in determining the wind speed necessary for capsize is the changing function of this system's center of mass, particularly the people inside. Most boat models involve boats that are much more massive than their passengers but mine will weigh around 75 lbs and carry 2 passengers.

- Qayaqs, now known as kyaks, were used by the Yup'ik Eskimos of Southwest Alaska. The Qayaq is a symbol of the Yup'ik culture. It symbolizes the significance of subsistence and using the surrounding resources to survive. This vessel also represents the intelligence and ingenuity of the Yup'ik people developing and designing a water craft that was swift, quiet, and could withstand harsh water turbulence. They were used as a mode of transportation for subsistence hunting and gathering. They were also a symbol of importance in society....   [tags: physics kayak kayaking qayaq sport sports]

- A boat floating can be greatly appreciated, especially if you are in the boat at the time. But what keeps a boat from sinking. Physics can explain these concepts. There are many forces that act on a sailing ship to put it in motion, but the buoyant force is what is required to keep the boat from sinking. A buoyant force is the normal force that pushes up on the boat supporting its weight in a fluid. The buoyant force "equals the weight of the fluid displaced by the object."(pg.427, Serway and Jewett) This concept is Archimede's Principle....   [tags: physics sail boat sailing boating]

- Sailing to Byzantium In W.B. Yeats, “Sailing to Byzantium” the narrator is an older man looking at his life with detest as the way it appears now. He is holding resent for the way the young get to live their lives and how he lives his now. The narrator is dealing with the issue of being older and his sadness of worth in this life, and who is later able to come to terms and accept his life. In “Sailing to Byzantium” the poem is broken up into four stanzas, each describing a different part of the voyage and the feeling associate with it....   [tags: W.B.

- Yeats’ Sailing to Byzantium       In "The Circus Animals' Desertion," W. B. Yeats asserted that his images "[g]rew in pure mind" (630). But the golden bird of "Sailing to Byzantium" may make us feel that "pure mind," although compelling, is not sufficient explanation. Where did that singing bird come from. Yeats's creative eclecticism, blending the morning's conversation with philosophical abstractions, makes the notion of one and only one source for any image implausible: see Frank O'Connor's comments on the genesis of "Lapis Lazuli," for example (211-22)....   [tags: Yeats Sailing Essays]

- Life of the Soul Revealed in Sailing to Byzantium and Shadows         The view of death from an aged individual can be one of acceptance of his life’s end or one of mystified wonder over the immortality of the soul. Both William Butler Yeats and David Herbert Lawrence take the latter view in their respective poems, "Sailing to Byzantium" and "Shadows." By viewing death as a continuation of their soul’s life in a different realm of being, they provide a comforting solution to the fear that death may be the end of their existence....   [tags: Sailing Byzantium Essays]

- The Hull of the boat is the frame which keeps the boat and its crew floating in the water. The mast is the tall pole that sits vertically near the center of the hull, the mast is what the sails are attached to to keep them suspended and straight. The boom is a large pole attached to the bottom part of the mast which is able to rotate up, down and side to side. The sails attach to the boom and the mast then the person controlling the main sail moves the boom around to change the direction and tension in the mainsail....   [tags: physics sport sports boating sail boat] 1562 words

- Sailing to Byzantium The poem, "Sailing to Byzantium" by William Butler Yeats, is an in depth look at the journeys of one man seeking to escape the idle and uneducated society of Europe. Yeats pursues a society of which sensual and artistic domains reign. The goal of the author is to become a part of Byzantine civilization and to be forever immortalized in the artwork presented in gold on the walls of the Byzantine churches. Immersion into a different culture and lifestyle is the only way to truly experience and fully understand the ways of this other culture....   [tags: Papers] 596 words

- Sailing "People either love it, or they hate it," Fred proclaimed again, for the umpteenth time. His reddish face almost glowed against the gray sky. The combination of giddy grin, round cheeks, and fine, yellow, tousled hair yielded a face far too boyish for a man in his mid-fifties. But the always-present twinkle in Fred's eye was ever so slightly diminished today, and I knew why: he feared that his intuition might be mistaken and that I might not, after all, take to today's activity....   [tags: Personal Narrative, Autobiographical Essay] 1309 words

As the angle of heel increases, passengers can lean to compensate or not lean at all and, there will be a natural angle of capsize in which the passenger+boat mass would prefer inversion rather than correction.
My solution, as applied to this problem, was to basically remove the boat and passenger weight from the equation by assuming the axis of rotation to be the center of mass and, that they do not contribute a torque force. And, since the boat and passengers are most of the mass, adding a sail and keel would change the natural angle of capsize very little.
So my initial problem of wind speed necessary for capsize will be in terms of reaching that estimated angle at which capsize will occur or, simply one that is comfortable. This model can now be thought of as a simple problem of static equilibrium where, when the sum of the torques at an angle equals 0, v will be the wind velocity necessary to reach that angle.
Some diagrams outline the torque exerted on the boat. Some distances are functions of the heel angle as well as the apparent area of the sail. These models consider the worst case scenario of full sail directly on the beam.
